FIXING RAILS 0N PERMANENT WAYS.

Specification of Letters Patent.

Patented May 20, 1913.

Application filed August 24, 1911.. Serial No. 645,860.

To all whom it may concern Be it known that I, ALBERT HENRY, of Paris,France, have invented a new and useful Improvement in Fixing Rails onPermanent Ways, which invent-ion is fully set forth in the followingspecification.

My invention relates to a device for looking within the wooden sleeperthe coach screws which fix the rail to the sleeper.

According to my invention metal pegs are forced into the sleeper fromthe end face thereof so that they engage between the threads of thescrew on each side thereof. This mode of locking the screws renders itpractically impossible that they should be torn from the sleeper untilthe latter iscompletely worn out. The method also allows of the use ofthe ordinary sleepers. The pegs are of iron, steel or any other suitablemetal; their cross section may be circular or polygonal.

My invention also comprises an apparatus constituting a centeringstirrup for the purpose of facilitating certain and rapid drilling ofthe sleepers for the insertion of the pegs.

In the drawings accompanying my specification:Figure 1 is a planshowingby way of example coach screws locked by cylindrical pegsaccording to my invention; Figs. 2 and 3 are transverse and longitudinalsections on lines MN and OP respectively of Fig. 1. i

It will be obvious that the following description relative to pegs ofcircular section applies equally to pegs of polygonal section.

The eifect of the pegs is to consolidate the sleepers by preventingcracking of the wood and by keeping the coach screws uprightparticularly in tender wood or in sleepers which are situated on curvesof the track of small radius and at places where point switches occur.They prevent the holes of the screws from becoming oval and also lockthe screws against withdrawal; on this account no foreign matter canslide between the wood and the screw. They form a resisting and securesupport even after many years and consequently facilitate the tighteningof the screws; moreover they make it necessary for the plate layer toforce in the screws solely by screwing for they prevent the screw frombeing forced in by ramming. Finally their presence in the wood does notfacilitate the penetration of moisture or foreign matters so that theydo not give rise to decay. They may be tarred or galvanized.

The pegs A which are cylindrical and preferably coned at each end areforced into the bores drilled before hand nearly tangentially to thescrews B; they engage between the threads of the screw and lock the stemthereof, which tends to separate the pegs and to drive them into thewood from each side. Two pegs may suffice, one on the side of the screwfar from the rail and as near the surface of the sleeper as possible,the other on the other side of the screw and as low down in the sleeperas possible. The distance between them however is a fraction of thepitch of the screw. A larger number of pegs may be used for each screwif desired. 7

Having thus described the nature of my said invention and the best meansI know of carrying the same into practical effect, I claim 1. Thecombination of a railroad sleeper having a rail thereon, a screwclamping said rail to the sleeper and pegs driven into the sleeper toengage between the threads on each side of the screw.

2. The combination of a railroad sleeper having a rail thereon, a screwfor holding the rail to the sleeper and means engaging between thethreads on each side of the screw for securing the screws in thesleeper.

3. The combination of a railroad sleeper having a rail thereon, a screwfor holding the rail to the sleeper and a peg in the sleeper engagingbetween the threads of the screw securing the screw in the sleeper.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
